Karry Challenge prompt: On the day before his wedding to Iris, Kara finds Barry having a panic attack.

The rehearsal dinner ended hours ago, however Barry stayed behind. Lost in his thoughts. He was glad all his friends were able to make it; especially the Legends, since they were constantly going through time.

Barry stood on top of Jitters' rooftop looking over his city. Everything seemed so calm and quiet. With the threat of Devoe floating around, it was nice to enjoy this little peaceful moment. Although, peaceful was the last thing Barry was feeling at the moment. He was thinking. Thinking about how he got here. Thinking about everything that has happened. And as he thought, he felt a small voice in the back of his mind telling him something was wrong.

Barry started to pace the length of the roof trying to figure out what was wrong and how he could fix it but came up short on an answer. He kept trying to pinpoint the source of his worry that he hadn't noticed he started to pace the roof at super speed.

"What has you all worked up?" came a voice from above.

Barry stopped and looked up to locate the voice only to find Kara floating down. She was still wearing the dress from the dinner hours ago.

"I honestly couldn't tell you." Barry replied as she landed on the roof, "I was up here just thinking, and I guess my thoughts started to run as fast as I can."

Kara giggled, "Wow, your mind must be in Star City by now." Barry laughed at her joke. "Maybe talking about it might help? And as someone with super-hearing, I've been told I'm a great listener." Kara moved over to stand next to Barry, overlooking Central City's night life.

"And people complain about my power puns." Barry chuckled. Looking out towards the city, he took a deep breath. "I don't know, I just feel like something is wrong here. I'm just trying to retrace my steps to find where I might have made a mistake, but I can't seem to find it."

"Maybe it's just pre-wedding jitters." Barry nodded contemplating Kara's idea, when her laugh brought him back to reality.

"What?"

"Nothing, just the Flash having pre-wedding jitters on Jitters' rooftop." Kara couldn't help but laugh at her own joke. "Kind of ironic don't you think?"

"You're just chalk full of jokes today, aren't you?" Barry asked looking at his friend.

"I guess, you're just making it too easy for me to make jokes." Kara responded.

There was a moment of silence that passed between them. It wasn't awkward. It was a comfortable silence that surrounded the two heroes.

It was finally broken by Barry.

"Have you ever wanted something your whole life and now that you have it, it isn't as great as you thought it was?"

Kara looked at Barry with confusion, "Um…"

"Like, have you ever wanted a toy. You begged and begged your parents to get it for you. Then when they finally break down and got you the toy, you realize that maybe you actually didn't want the toy?"

Kara was still looking at Barry like he had a third eye on his forehead, but then something clicked. Barry was all alone the night before his wedding day, pacing on a rooftop looking nervous and stressed.

"Barry are…are you having second thoughts about marrying Iris?" Kara asked looking into his eyes.

"I…uh, I…I am." Barry turned away from Kara with a deep sigh, almost ashamed of what he was saying. "Everything seemed perfect; the future newspaper, and the fact that our Earth-2 doppelgangers are married. It should have been enough to seal our fate, but everything that has happened; Flashpoint and Savitar, I feel like Iris and I don't really fit together as well as we thought."

Kara moved closer to Barry. "Hey, it's ok. Things like this happen. Something seems good on paper but when it comes to the real world, it just doesn't work."

"There's more to it." Barry said leaning on the roof rail, tucking his head down.

"Like what?"

"When I went back to normal from my Speedforce haze, Caitlin and Cisco told me what happened in the six months of my absence. Cisco told me how Iris was so against trying to get me back from the Speedforce. Doesn't that seem odd to you? Maybe it's just me but if my fiancé was trapped in some unworldly dimension, I would do everything in my power to get her back. I mean wouldn't you do everything in your power to have gotten Mon-El back?"

Kara quickly looked away from Barry so that he wouldn't see the hurt on her face. The thought of Mon-El still stung. After six months of wishing he would come back, he does; only he's married.

"I'm sorry. I was thinking." Barry tried to apologize.

"No, no it's ok." Kara waved him off. "I get what you mean. If there was a way to get him back before he shot off into the future, I would have exhausted ever possible option."

Barry studied her face. Deciding what to say next.

"There's still one more thing that's stopping me from marrying Iris." Barry said taking a step closer to Kara.

"What's that?" Kara looked up, noticing quickly how close Barry was. He was less than an arm length away. Even though it was night time. She could see the green of his eyes.

"You."

"Me?" Barry nodded as a response.

"Kara, ever since I accidentally jumped to your world and saved you…"

"I didn't need you to save me." Kara interrupted.

"and have you fall to the ground from a sky scrapper without a scratch and have your identity blown? Yeah, you definitely needed saving." Kara chuckled. "Anyway, ever since then, I just feel like we go together perfectly. There's this connection between us. And we always have fun on our adventures, you can't deny that."

Barry turned away from her.

"There's something I've never told anyone about." Kara noticed that Barry looked nervous as to what he was about to say.

"And you're going to tell me?" asked confused, why would he share this secret with her?

"Yes. Uh…you see, when I came out of the Speedforce, I was in a state of limbo. To the outside world I was gone six months, but in Speedforce time it could've been a milenia." Kara listened to Barry's words with anticipation. "When I came to, I told everyone that I only remembered going in to the Speedforce with my mom and stopping the samurai that kidnapped Iris. But that was a lie."

"Then what's the truth Barry?" Kara asked, seemingly on edge.

"I remember my time in the Speedforce. I was forced to relieve my life over and over. Eventually I learned that I was able to change my choices and receive different outcomes. In a lot of my lives, I chose to stay on Earth-38 with a certain Girl of Steel." Although Barry couldn't see it, Kara blushed. "We lived a happy life together. Well a happy enough for two heroes, but we were happy. And now that tomorrow I'm to be marrying Iris, I can't get the thought of living that life…with you."

Barry stepped forward, grabbing both of Kara's hands into his.

"Kara, I am not the type of guy to have a mistress or cheat. I am telling you this right now. I have deep feelings for you and I would really like to explore them. I will tell Iris about not wanting to get married. And I know you are still not over the whole Mon-El and time travel situation. But if you're willing to give this a chance when you're ready; well I am too."

Kara couldn't believe what she was hearing. Barry Allen has feelings for her. She would be lying to herself if she said she never thought of Barry in that way before. I mean the two had a lot in common. And he was right, they did have a lot of fun together. So maybe seeing where this went wasn't a bad idea after all.

However, she still was still getting use to her Mon-El ordeal. And the fact that they live on two different Earths makes their potential relationship impossible. But Barry Allen was the impossible, he could make anything happen, right?

"Kara?" Barry's voice brought her back from her own mind. "Can you please say something? I'm kind of losing my mind here." He gave her a nervous smile.

"Sorry, sorry." Kara responded shaking her head. "Barry, I am not ready to put myself back out there."

Barry looked down at the ground. Slowly dropping their joined hands. He was about to let go of hers, when Kara gripped his hands again. Barry looked up at Kara.

"But if you don't mind waiting until I am ready, I would like to get back out there…with you that is." Kara smiled.

Barry engulfed her in a hug. She knew she wouldn't be ready a few days, but by the hug alone; Kara knew Barry was going to help her through her rough times.

After a few minutes hugging, Barry let go of the Kryptonian.

"I guess I should find Iris and have a little talk." Barry looked a bit sad

"Hey, it's going to be alright… I think? I don't know, I've never done that before. Gosh, it's going to be really awkward once she finds out an alien abducted her fiancé."

"Gee Kara, you sure know how to give a pep talk." Barry laughed.

"Sorry, I'm sure she'll understand. Just be honest with her." Kara offered as advice.

"God, Joe might kill me and don't get me started on…"

Barry was interrupted by a giant portal opening over Central City. "Oh, this can't be good." Out of the portal came a ship that looked similar to the Waverider. However, this Waverider had Nazi symbols all over it.

"Looks like a hero's job is never done." Kara said gathering her suit from her purse.

"I guess not." Barry sent an emergency alert to all his friends. All hands-on deck for this one.

"You ready for this Flash?" Kara turned to Barry, already suited up.

Barry disappeared and reappeared in his new Flash suit.

Barry grinned at Kara, "Up, up and away"
